Home is always the last, the warmest harbor, and it is the place where every wanderer who wanders outside wants to dock when he is tired.

Of course, when Wang Yinan, who was like an arrow, passed through Deshi, he didn't forget to go to the precision instrument manufacturing factory to chat with his little Deng Weiguo, and then give everyone a big red envelope, you know, whether it is the manufacture of superconducting materials or the small motor on the flying carpet, it is inseparable from the precision equipment made here.

When I returned to Cotton City, it was already dusk, Wang Yinan bought a big house with a jump in the high-end community of Binjiang for his parents, originally wanted to buy a villa in the suburbs, and then the old couple felt that they didn't drive, and it was too troublesome to live in the suburbs, not to mention that the villa was deserted and untouched, and it was more comfortable to live in the community.

So not far from the research institute, I bought a large duplex apartment, this time Wang Yinan's sister, Wang Yishu was very happy, after all, I have my own boudoir that can be well decorated. Wang Yishu is already in his third year of high school this year, and his grades are still quite good, anyway, he is sure that he will be admitted to the imperial capital to be the second generation of rich.

Although Wang Yinan is of the same generation as her, there is a local tyrant brother, who is barely a rich second generation.

I heard that Wang Yinan is back, this time it is completely different from last year's homecoming, although Wang Yinan was famous last year, he is not just a young and promising scientist, and now, Wang Yinan is a world-renowned mathematician, physicist, the youngest Abel Prize winner, the youngest professor at Imperial Capital University, any title can be taken out, it can intimidate a group of people.

No, although my parents have long since retired, but the director of their research institute still came to visit the retired employees of our institute twice a year ago, and the meaning of the drunkard is not in the wine is also obvious, in addition, the director saw that the factories in 116 and Deshi City were thriving, and he also wanted to find the boy of the old Wang family to see if he could get something good for himself.

Drinking with classmates, eating Chinese New Year's Eve dinner, or this kind of second- and third-tier cities are more of a New Year's atmosphere, Chinese New Year's Eve The deafening sound of firecrackers, but in the imperial capital for many years has not experienced Feel, Wang Yinan and his sister also ran to the street, all kinds of ceremonies, crackers, and firecrackers like bombs, all had a good time.

After two days, on the second day of the Lunar New Year, the guests began to come to the door in an endless stream, which was even more scary, and the mayor of Cotton City also ran to Wang Yinan's house to visit, which was called New Year's greetings, of course, he expressed his dissatisfaction with Wang Yi's boys' shoes to open the factory in Deshi instead of cotton.

There was no way, Wang Yinan had to swear that the next factory would definitely be in cotton, and the fertilizer and water would not flow into the fields of outsiders.

Engaging in politics requires looking at the direction of the wind, the top bosses are coming, and the subordinates have to have a few dares not to keep up, so the Science and Technology Bureau, the China Merchants Bureau, and the Education Bureau, all the heads and brains who can get involved in a little bit of the relationship almost didn't break the threshold of Wang Yinan's house.

In addition to all kinds of immortals, there are also many relatives and friends, including friends of Wang Yinan's parents have also come to visit, and most of them are here to ask Wang Yinan, "Our children have good grades, can you, cough cough cough, you know, it is said that Imperial Capital University has a lot of special recruitment places."

In the end, Wang Yinan couldn't stand the endless entertainment, so he left home in a hurry on the fifth day of the Lunar New Year.

The first stop is Shudu, and Mr. Yang has not had a good year, because of Xianglong's power consumption problem, the two of them made an appointment to chat in the old teahouse in Shudu, this damn solar panel is not powerful enough, what should be done.

The teahouse in Shudu is still very distinctive, Xiao Er holds the teapot and shuttles back and forth between the lobby and the private room, the teapot is very large, it is estimated that it is very difficult to lift it, but the more exaggerated teapot actually has a meter-long spout, when the guests want to add water, Xiao Er throws the teapot spout from afar, and the boiling water is accurately poured into your teacup from the one-meter-long spout.

"If a guest asks curiously, pretend to be X", "Without him, only familiar with his hands", "Just live", Wang Yinan complained while watching Xiao Er's performance.

The sun shines on people on the winter afternoon, not hot at all, but a little warm and comfortable, and there is no man with glasses talking about "blockchain", "ABC round of financing", or "is it enough to transfer 10 million soft girl coins to you first" or the like.

Wang Yinan thinks that Shu is still real, everyone is discussing how much they have won in mahjong, and where will they go to eat delicious.

Sighing comfortably, Wang Yinan said to Chief Chef Yang, who was concentrating on making tea, "I forgot to ask you last time, how is our joint engine research laboratory now?" ”，

"Very good", said Mr. Yang,

"The five-ton engine has reached the advanced level of Bluestar, and the thrust-to-weight ratio has reached more than 12",

"Damn, such a cow", Wang Yinan was startled,

"It seems that the latest F119 of the rice country is less than 12,

Chief Engineer Yang shook his head, "F119 is not the most advanced, F135 is, thrust-to-weight ratio has reached 13",

"But that engine is a bit weird, supersonic performance is not good, so basically, we are at the five-ton level, reaching the No.1 of Blue Star."

"That's also very good", Wang Yinan has been mixed with the airline for so long, and he is not a novice,

"Although for a manned fighter, this thrust is still a little smaller",

"Basically, if it reaches nine tons, it can be used as the power of a medium twin-engine fighter."

"But the power used to make a drone is very suitable",

"I don't know how big and how the fuel consumption is", Wang Yinan asked,

"It is inconvenient to say the specific data on such an occasion", Chief Yang is still very cautious,

"But it's definitely a blue star super-first-class",

"Thanks to the combustion chamber simulation calculations you provide, the effect on improving the combustion efficiency of oil is still very obvious."

Pouring tea on the teacup in front of Wang Yinan, Chief Engineer Yang still looked sad, "I'm not worried about the engine, judging from the results of simulation calculations, the temperature can continue to increase, and there is still a lot of room for improvement in performance."

"It's just that this problem of too much power consumption is really difficult to handle."

"Our team has calculated, we have corrected the aerodynamic shape, and then tap the potential of the fuselage, which can reduce the drag a little, increase the lift a little, and reduce the speed of a part of the propeller, that is, it can reduce the power consumption a little", said Chief Engineer Yang.

"However, the surplus power that can be left for charging is still too small."

"What about increasing the output power of solar panels?" , Wang Yinan asked,

"It's too difficult," said Mr. Yang.

"We have consulted experts in this area, and some research institutes do have some new solar panels, but the efficiency is only two percent higher, and the cost is more than five times higher."

"It's just not a good deal."

"It's useless to increase the battery, and now the key problem is not that the battery is not enough, but that there is no spare power to charge the battery, so the weight of the drone should be reduced instead", Wang Yinan said.

"I'll call a certain institute in Jinling of the Ministry of Electronics to see if they can compress the weight of the equipment and save a little bit."

After Wang Yinan finished speaking, he called Director Ma in Jinling, "Director Ma, I'm Wang Yinan, happy New Year",

"yes, what, you've already started?" ，

"Hard, hard, calling you, there is a small problem",

"It's not your problem, we've re-evaluated the weight of the sky now, and we think it would be better if the drone was lighter",

"Yes, all subsystems are being cut, how much weight can you save there, go back and give me a number",

Putting down the phone, Wang Yinan said to Chief Teacher Yang, "They will give a figure after evaluation, and you can estimate it according to the reduction of 20%."

"It's still not enough, this solar panel is too pitted", Mr. Yang still muttered worriedly.

Science is like this, if you can't do it, no matter how much money you spend, no matter how determined you are, you still can't work overtime every day.

I soaked in the teahouse with Chief Yang for most of the day, and thought of a bunch of tricks, but the problem was still not completely solved, and Wang Yinan had to put this matter aside for the time being, and the next stop was not the imperial capital, but the small city in the south of the Yangtze River, Gusu.

Of course, to be precise, Gusu is no longer a small city, due to its proximity to the magic capital, many IT equipment manufacturers who do not put their factories in the magic capital for cost considerations have opened factories in Gusu, resulting in high housing prices here.

Moreover, Gusu was the capital of Wuyue during the Warring States Period, close to the edge of Taihu Lake, with beautiful scenery and unique geographical location.

There is a high-speed railway in Shu to Gusu, but it is not a straight line, you need to go to Chang'an first, and then cross the Yellow River and the Yangtze River from the north to Gusu, the high-speed rail along the Yangtze River is still under construction, and it is estimated that it will take several years to open.

This route was too long, it took more than ten hours, and Wang Yinan really didn't have so much time, so he had to fly to the magic capital early the next morning.

It is a ten-minute journey from the magic capital to the Gusu high-speed railway, Wang Yinan came to Gusu at this time, of course, to meet his mother-in-law.

Zhou Hui's father died not long after returning to China, leaving her and her mother alone, except for her mother's family in Gusu, most of the other relatives and friends are abroad.

Zhou Hui looks really similar to her mother, and the two of them stand together, like sisters, Wang Yinan, a handsome and shy little boy, that is the most popular among middle-aged women.

It didn't take long for Zhou Hui's mother to completely stand on Wang Yinan's side, helping to figure out how to marry her daughter out quickly.

"Mom, I'm a little skeptical about whether it's your own birth", Zhou Hui was angry, hugged his mother's arm and began to go crazy.

And where can Zhou Hui's mother take care of her, busy picking up vegetables for her prospective son-in-law, "Eat more of this",

"The smoked fish here is very good, the authentic taste of the magic capital, it has been a time-honored brand for decades, and I ate it when I was a child."

"Authentic Demon Capital Raw Fried Buns, Xiao Wang, you eat one more",

Wang Yinan still had a small longbao stuffed in his mouth and couldn't answer, Zhou Hui couldn't stand it, "Mom! ”，

"Your daughter hasn't eaten yet!" ，

"Hurry up and eat it while it's hot, isn't there still a full cage here", Zhou Hui's mother casually perfunctory,

After eating this meal, Wang Yinan's stomach burst and he sweated profusely, and Zhou Hui drove him back to the imperial capital directly, and the reason was very simple,

"Let's go quickly, you come to compete with me for favor, stay for two more days, I suspect that our mother will have a son and forget her daughter."

Therefore, from the perspective of family happiness, I advise you to plug in the door.

The mother-in-law is much more reasonable than the mother-in-law.
